Abstract

PURPOSE:To facilitate and ensure the preset, by providing a control device, which can select characteristics electrically, and a display device in the equalizer device of a car stereo which can switch the two-speaker system and the four- speaker system. CONSTITUTION:An optional frequency characteristic is given to the audio signal of a car stereo through amplifiers 1L and 1R, and this audio signal is outputted. A reactance circuit 3 is connected to amplifiers 1L and 1R through a control circuit 2 to given an optional frequency characteristic to them. A data input device 4 consists of push-button keys and lamps such as LEDs, and data which gives a required frequency characteristic is given to the device 2 through a preset data input device 6 and a memory 6 by key operation. A display device 7 displays switching states of changeover switches 14L and 14R for the two-speaker system and the four-speaker system. By this constitution, characteristics of amplifiers 1L and 1R are selected only by the operation of preset keys of the device 6, and the characteristic selection state is seen.
